The fifth graders have been learning about the process engineers go through to find solutions to everyday problems. To practice the design process, students used modeling clay to design a raft that would float. Then they added pennies to the raft until it sank. They worked through the design process, by redesigning their raft, or by placing pennies in the rafts in different positions, to find the most pennies the rafts could hold without sinking. The students had a lot of fun designing and sinking their rafts.
